3.1 Console Audio Connections
SD Series console external audio connections can be made using either BNC MADI (AES10), Optocore or the DiGiCo Cat5e
Connection.
There are 2 types of MADI connecftion available. A DiGiCo Stage rack can be connected to a console via a bi-directional MADI
connection will have upto 112 channels (56 n, 56out) of audio plus the control data for the Rack (located on CH57). A Bi direc-
tional standard MADI stream will contain upto 128 channels of Audio (64in, 64out) and can be connected to any 3rd party device
that has MADI connection.
A DiGiCo Cat5e connection is a Bi Directiional up to 64 Channe l interface that uses STP Cat5e Cable with interference suppres-
sors fitted on each end used to connect D-Racks and SD9 and SD11 Consoles.
3.2 Multi-Console setups
3.2.1 FOH & Mons sharing a stage DiGiRack (MADI) ..................
It is possible for 2 SD7 consoles to share the inputs from a remote DiGiRack by using the 2 sets of MADI ports on the rack.
In this situation, only one of the consoles can control the rack functions such as the analogue gain of the mic pre amp and the
phantom power switching.
The suggested setup for two SD7 consoles which are sharing the same racks is as follows:
FOH & MONITORS
WITH DIGIRACKS
USING MADI ONLY
MONITORS
Audio Sync = MADI IN ON PORT 1
Uni-Directional Gain Tracking
FOH has control of the Analogue Gains

When using DiGiRacks on MADI, because each SD7 has 2 engines there is a requirement to split the rack's MAIN and AUX MADI
OUT signals to feed the second console's MADI IN ports.
The recommended connection between the Monitor console and Stage Rack is a single MADI OUT from the Stage Rack's AUX
MADI connected to the console's MADI 1 IN..
The FOH (Master console) is connected via MADI IN and OUT to the stage rack.
A similar method can be used if the Monitor console requires gain control and the FOH console will track the gain changes.
MADI OUT from the Stage Rack's AUX MADI connected to the FOH console's MADI 1 IN..
The Monitor (Master console) is connected via MADI IN and OUT to the stage rack.
